Electricity & Magnets
Terms in this set (21)
the buildup of electrical charge on a material
a movement of charge
material that electricity flows easily through
Examples: metal, water
material through which electricity does not flow
Examples: wood, air, rubber
a discharge of static electricity from a huge cloud called a thundercloud
when energy moves through an object that has been struck by lightning and goes into the ground
the path that electricity can move through
the electricity that flows through a circuit...it is a moving electrical charge
there are no breaks in the path that electricity moves through...the path is complete
no current will flow through it because there are breaks in the path....the path is incomplete
controls the current in a circuit (opened and closed)
a poor coductor....current does not flow easily through it but allows electrical energy to be changed into other forms of energy (such as light and heat)
Examples: filament in a light bulb
a side circuit of very low resistance that occurs by accident...dangerous.
changes chemical energy into electrical energy.
electricity can flow in only one way
connects two objects to the cell and has two paths through which current can flow
a device that keeps too much electrical current from flowing through wires
a switch that protects circuits.
when current flows creating a temporary magnet. It can attract all items made of iron, steel, nickel, and cobalt...very powerful
a device that changes electrical energy into mechanical energy and can be used to power items like refrigerators
changes mechanical energy into electrical energy called an alternating current.
